NASA's Maven spacecraft detects dramatic changes in Mars atmosphere

[Alfonso Maruccia]

The big picture: Solar wind is a stream of electromagnetically charged particles released from the upper atmosphere of the Sun, the corona, and it permeates every planet and cosmic object in the Solar System. When something changes in the amount of charged particles, unexpected and extreme atmospheric phenomena can be observed.

The Mars Atmosphere and Volatile Evolution (or Maven for short) spacecraft has been orbiting Mars since September 2014, with the task of studying how the planet lost its atmospheric gases throughout the eons. In December 2022, Maven witnessed an unexpected expansion phase of the Martian atmosphere.

The spacecraft detected a dramatic "disappearance" of the stream of charged particles making up the solar wind, NASA has now revealed. The phenomenon was created by a solar event so powerful that it created a "void" in its wake as it traveled through the entire Solar System.

Like any other planet in our little cosmic neighborhood, Mars is constantly immersed in the solar wind. The particle flux exerts pressure on the planet's magnetosphere and ionosphere, ultimately driving small chunks of the atmosphere away to outer space. The extreme solar event detected in December 2022 was caused by faster-moving solar wind particles overtaking slower moving solar wind, NASA explained.

The complex interaction between the two types of solar winds acted as a broom, sweeping and compressing the two regions together and creating a "rare void" of extremely low-density solar wind region in its wake. According to Maven's observations, the solar wind battering against Mars was essentially gone, and the planet's outermost regions reacted accordingly.

The density of the solar wind dropped by a factor of 100, causing a dramatic reduction in pressure against Mars' magnetosphere and ionosphere. The two regions of space surrounding the planet were thus able to expand by thousands of kilometers, more than triple their typical size.

The ionosphere showed other remarkable changes, going from its usual magnetized state to an unmagnetized one. Meanwhile, the layer between the solar wind and Mars' magnetosphere became "unusually electromagnetically quiet," NASA explained.

The extreme conditions observed in 2022 are "scientifically invaluable," Maven principal investigator Shannon Curry remarked, as they provide a way for scientists to see how Mars could behave if it were orbiting a less 'windy' star. The Red planet would be a very different world without the extreme pressure exerted by the solar wind, and Maven was specifically designed to study these types of interactions.

Climate change happens everywhere, throughout billions of years, who would've thought? With or without human.

And here we are arrogantly thinking that we are "that great " to be able to forcefully change our planet cycle.

Really? U sure? In Pa, they laid down the Pa Turnpike starting in 1940. After it was done, there was a dramatic drop in lake effect snow from the great lakes, south of the highway.
The turnpike created a huge crosswind that lowered lake effect snowfall south of it as much as 40% at times. Permanently. They didn't even know they were doing it.

Next, there is a small company in Texas doing cloud seeding. I saw the story on The History Channel.

"Rain output from seeded storms, on average, was 24 percent more than that from nearby untreated storms."

Some people should look into the old proverb:
"It is better to remain silent and thought of as a fool, than to speak and remove all doubt"
This thread proves that.

And here we are arrogantly thinking that we are "that great " to be able to forcefully change our planet cycle.

From NASA. Notice anything unusual not long after the industrial age? Me too!!!

Temperatures and atmospheric concentrations of carbon dioxide over the past 66 million years. Bottom numbers indicate millions of years in the past; right-hand numbers, carbon dioxide in parts per million. Hotter colors indicate distinct periods of higher temperatures; deeper blues, lower ones. The solid zigzagging line charts contemporaneous carbon dioxide levels; shaded area around it reflects uncertainty in the curve. (Adapted from CenCO2PIP, Science 2023)

Let's go to planet's history for once. Not just less than a million years. Check the mark approx 16 million years ago, not to mention 50 million years ago. And that's barely 1% of our planet's history.

It all comes down to what suits you better. Ice age where we currently still are or the warm fuzzy and acid planet. None the less this is way more complex than the media is presenting. And some agendas are trying to cash in this way or the other.

First show me a person that was recording something 500yrs ago ...this hoax of climate change has nothing to do with man, nothing man does or doesnt will every totally affect the weather so significanly that the world will die, nature will kick mans *** over 1000 times before we get strong enough to make changes.

Do you honestly not know how the ancient data is collected?
Kind of shines a bright light on the rest of your............ "thoughts"

it shines a light of your lack of understanding how data is collected not was collected, because they use tree rings. A tree that is 4000yrs old on the earth now is about as wide as a house if it was still alive, so that proves how stupid climate change pushes are, tree's collect carbons which is what forms the rings over a season which is roughly 1 yr, just some basic science so lets take a tree that 4000 years old, talking about bigish trees, 4000 rings avg around 2cm = ...you don't want to know how much bs the scientist talk

the diameter of a circle that grows by 2cm, 4000 times. If that’s correct, then the diameter of the circle after 4000 growth cycles would be approximately 1,073,741,824 cm or 10,737,418.24 meters.
Just work that out in your science....
Most science is thumb suck, but that is ok not long and all will be revealed....

I have no idea where you came up with these numbers.

I have seen trees that gained an inch a year in diameter. This was in a temperate climate. This was also a "hardwood", (Broad leaved deciduous), which are often referred to as "explorer species". due to their rapid growth. The conifers tend to come to an area later and are much longer lived. When you consider a, "century oak" is considered an "old tree", you'll see hat I mean.

Conifers come in later, are much longer lived, and grow many times slower. In fact, the harsher the climate, the slower they grow..

Ginko biloba, is ostensibly a "conifer", and can attain ages close to 1,000 years.

Several spruce species are used as guitar tops, most often sitka (Picea sichensis), as it's the largest of the genus. However, red spruce, is considered to be superior for the purpose. "Adirondack" spruce is considered to be the best of the bunch. In reality, it's merely a variety of red spruce that grows in higher elevations and in a harsher clime. As a result,the grain is very tight. So a year's growth might only add about 1/8" to the diameter, (or about 2 mm or less if you prefer).

So, really old trees: https://en.wikipedia.org/wiki/Bristlecone_pine

Sitka spruce: https://en.wikipedia.org/wiki/Bristlecone_pine

Red spruce: https://en.wikipedia.org/wiki/Picea_rubens

And just for laughs ginkgo: https://en.wikipedia.org/wiki/Ginkgo_biloba

BTW, you must be either young or under informed about climate change. A couple of decades ago, we almost blew a hole in the atmosphere's ozone layer with the propellants from spray cans of hairspray. To this day air conditioning propellants must be captured and recycled, as well as their chemical structure having been changed to minimize atmospheric damage. (No more good old R-12, it's R-134a now). Chlorofluorocarbons I believe, were the culprits. https://en.wikipedia.org/wiki/Chlorofluorocarbon

So, to say that man isn't destructive or capable enough to damage the earth's climate, is, for want of a better term, a bit naive.

That is some of the most dreamed up numbers I have heard in years.
Not to mention, tree rings are NOT widely relied on to read past carbon dioxide levels.
And how would that even work? The oldest trees in the world are approximately 5000 years old.

Those facts are gathered with core samples. In those frozen samples are air bubbles that, obviously, still has air in them from anytime in the past they want to look. They just get the samples from a greater depth. Its called basic knowledge.

We all await your brilliance on the temperature readings tracked over millions of years in the cited post.

And how we've scientifically proven your "frozen air bubbles" neither gained nor lost carbon in hundreds of thousands of years they were buried (hint: google leaching).

Did you know that air dissolves in other stuff? No poop, really.!

In fact, that's why fish tanks have aerators. Since fish can't "breath water", they can only separate dissolved oxygen from water. They can't "distill", or, "crack" oxygen from H2O. Air has to be present in the water or fish will die.

Then too, water will permeate solids. surely you've experienced this by stepping in a puddle, haven't you? Well guess what, that water in you poor soaked sneakers, has dissolved air in it. Are you starting to catch on yet? Have you ever heard of a mass spectrometer?

Then again, you probably haven't. After all, they're not made by AMD, Intel, or Nvidia, and they aren't used for gaming.

There's no evidence that CO2 proxies are capable of 'recording' with any accuracy very brief/short-term spikes (or drops for that matter) in atmospheric CO2 levels. This has been well documented from ice cores in the past. It's impossible to determine with any accuracy what CO2 levels may have been like over intervals as small as the industrial age, in the long past. It's only via extraordinarily sensitive man-made instruments that we're able to measure the current levels to the ppm (instruments made possible by the industrial revolution and fossil fuels).

Ancient data lacks modern precision and granularity. It is, quite literally, impossible to determine CO2 levels on, say, Dec 15, 3482 b.c.
